Description martin.naewe 2016-04-02 15:15:48 UTC 
Aim: Video should shine through the characters of the title which is zoomed in. 


Reproducible: Sometimes

Steps to Reproduce:
1) Add a video to track 2.
2) Create title clip with some white text, add blur and create animation to zoom in a character completely, e.g. "Title" -> zoom in the dot of the "i"
3) add title to track 1
4) add darken effekt

Play in the project monitor, move cursor back and forth, or edit again the title clip. 
Sometimes, it will crash.

Happend under Ubuntu 15.10 (on default package) and Kubuntu 16.04 (with kdenlive ppa, current version)

Martin, can you please try with recent stable 16.04.2 and at least MLT 6.2.0? There has been an important fix to the title rendering module, finally killing a longstanding bug. Please be so kind as to report back your results and please close this report if the bug has gone.

Can't reproduce with today's build.
